Example of a LOR from an employer

My boss asked me to write my LOR for him and I was wondering if anyone knows a place to find examples of LOR's (specifically one from an employer). If anyone has used a letter from an employer that I could get some ideas from that would help a ton. Any advice is welcome

I have searched around on "all seeing" Google and I couldn't really find anything that dealt with a letter from an employer regarding law school. There is a bunch of sample letters from professors and sample letters directed to the professional world but not specifically to law school. any other ideas??
